I had this problem as well and fixed it by deleting gen_py in my temp directory.

You can find this folder here:

C:\Users\USERNAME\AppData\Local\Temp\gen_py

Thanks. I could not access the folder through windows. So, I used DOS, located the exact path and renamed the folder. – Fred Mar 02 '22 at 08:00
